Advice for N910F lightweight and battery friendly ROM

Hello,

I am asking for your contribution in order to find a ROM that provides good performance while giving good battery life.
I am using Emotroid v8 but I find that the ROM implements lots of stuff I don't need (customisation, themes...)
I want a debloated ROM, Touchwiz or stock (I would prefer stock though)
What would you suggest?
Thanks for your answers
